How To Read Smd Capacitor

Click here for resistor colour code and smd resistor code ceramic disc capacitors have two to three digits code printed on them. The only way to read the value of these sm capacitor is via a capacitance meter.

How To Read Capacitor Code Value Ceramic Capacitor Code Chart

A capacitors storage capability is measured in farads and is called capacitance.

How to read smd capacitor. But most sm capacitors values are not identified in any way by visualising most of them think that they are identified according to there size but size of the components does not indicate the capacitance as each capacitor has a different number of layers according to there manufacturer. Method of finding the valuemeaning of codes of capacitor. Be carefully when you write a post you can confuse to others.

Unlike resistors capacitors use a wide variety of codes to describe their characteristics. The thru hole part kludged onto smd pads will put a lot of stress on those pads and the solder. If you read 104 in the capacitor it means 100000pf so the real value is 100nf and not 10nf as you said.

Most capacitors are measured in microfarads or in picofarads. Their performance is also very good some performing particularly well at rf. There are many different capacitors that have many different sorts of markings.

Often smd electrolytic capacitors are marked whit the value and working voltage. This is particularly important because it is necessary to be able to check the polarity and to have a marking to identify the polarity of the capacitor. How to read a capacitor.

Smt smd capacitor smd smt surface mount capacitors are the most widely used for of capacitor today being small leadless and easy to place on a pcb they are ideal for high volume manufacture. This article will guide you through the basics of how to read the most common capacitor. The first two numbers describe the value of the capacitor and the third number is the number of zeros in the multiplier.

One farad is a very large charge and few capacitors have that capacity. Voltage polarity tolerance and capacitance can be displayed in different ways from one capacitor type to another or from one manufacturer to another. Physically small capacitors are especially difficult to read due to the limited space available for printing.

The markings on a capacitor indicate the charge it can hold and the tolerance of the rated capacity. The only way to know for sure is to read the datasheet. Smd tantalum capacitor markings in some cases the only marking shown on the capacitor may be a bar across one end indicating the polarity.

Yes you can replace a smd capacitor with a thru hole of the same rating as long as you can mechanically do it and the decreased ruggedness is acceptable to you. Guillermo added after 2 hours 52 minutes.
